Therefore the mechanical performance requires a better understanding, especially in the presence of open holes.
The mechanical behavior of notched FMLs is very complex due to their specific features like heterogeneity, anisotropy or strain gradients.
As part of the notch sensitivity study, unnotched coupons are also tested to determine the unnotched tensile strength and in-plane laminate mechanical properties in accordance with ASTM D-3039.The damage characteristics are determined after chemical removal of the outer aluminum layers.
These axial splits blunt the notch, hence reduce the stress concentration factor.

Researches on the properties of steel after a fire are still in the initial stage and under development yet.
After cold bending 180°C under the normal temperature of steel, each specimen was in good condition, there was no peeling, cracking or any other observed damages, all the specimens satisfied the requirement of impact toughness properties.
The appendix J of CECS252:2009 has provided steel yield strength reduction factor after high temperature.

The first type of material under development is a photocatalytically active admixture in powder form, allowing the preparation of concrete surfaces with photocatalytic properties.
The second type of material under development is a photocatalytically active cement admixture in powder form, allowing the preparation of concrete surfaces with photocatalytic properties.
During the second stage of the project a total of 36 various recipes for plasters and admixtures were proposed, and all 36 of the proposed materials were produced by BETOSAN s.r.o. at their Batelov plant, ready for tests of workability, physical and mechanical properties.
The individual recipes were subjected to experimental verification of their physical and mechanical properties and the results were compared with reference recipes.
The goal of the proposed experiment is to evaluate the effectiveness of antimicrobial (especially anti-algae) activity of the provided samples of photoactive plasters and concretes, “in situ”, in other words placed so that they will be exposed to the abiotic and biotic factors of a regular outdoor environment.

Liu Hongli [3] used VE on the manufacture selection of complex product, she analyzed function and value of the main factors which influence the product quality and cost,optimizing the existing scheme.
The friction gaps affect the closed nature of the combustion space between piston and hole.

However the mechanical property of the PVDF porous membrane prepared by wet phase inversion method is not satisfactory.
Membrane distillation has many desirable properties such as low energy consumption, ability to use low temperature heat, compactness, and perceivably more immunity to fouling than other membrane processes [3].
Scaling on membrane surface was a main factor resulting in membrane fouling in MD desalination.
The operation conditions, such as the concentration of feed solution, operation temperature and flow rate, would affect the speed of membrane fouling in MD process, among them the concentration of feed solution was the most important factor [7].
When the fabric support was finished with 2g/L FK-510, the composite membrane had better mechanical property and better fouling resistance.

The specification of the probes is in line with international standards, including pore water pressure probe, and modules of temperature, seismic waves and video probes etc, which enabled to obtain rapidly and accurately basic physical properties.
The calculations of Su are mainly through theoretical approach (based on capacity theory, cavity expansion theory, strain path theory etc.) and empirical approach, Undrained shear strength is related to lots of factors including the soil stress history, anisotropy, strain rate, failure plane orientation etc.
The excessive porewater pressure method The above two figures show that these two methods for estimating Su deviate greatly, changes of porewater pressure significantly affect the results.
(4) The undrained shear strength of clay estimated by the theoretical method should multiply with the corresponding revision factor.
